201141291 六、發明說明： 【發明所屬之技術領域】 本發明之特定態樣大體而言係關於無線通信，且更特定 言之，係關於同級間通信之排程。 根據35U.S.C. §119之優先權主張 本專利申請案主張2009年10月29曰申請之臨時申請案第 6 1/255,993號之權利，且該臨時申請案已讓與給其受讓人 並以引用的方式明確地併入本文中。 【先前技術】 為了在與一個存取點（AP)相關聯的兩個使用者站台 (STA)(例如，STA1及STA2)之間傳輸資料，通常可用兩種 方法。在一方法中，STA1可將資料發送至AP，且接著AP 將該資料轉遞至STA2。在另一方法中，STA1設定與STA2 之直接鏈路設定（DLS)連接。經由AP轉遞用於DLS之訊 息。一旦設定了 DLS連接，STA1即可將資料封包直接發送 至 STA2。 目前，必須使用基於載波感測多重存取（CSMA)之競爭 協定來發送使用DLS傳遞之訊框。然而，在存在若干DLS 連接之情境中，可能發生顯著衝突，其可減少該多個DLS 串流之輸送量。 【發明内容】 特定態樣提供一種用於無線通信之方法。該方法大體上 包括：判定裝置之間的多個通信之一排程，其中該排程指 示由一第一裝置用以傳輸之一時間週期及由一第二裝置用 151920.doc 201141291

輪s旬（PSMP)訊框）用於同級間通信之基於Ap之排程，該等 同級間通信係諸如圖2中所說明之無線節點2〇2與無線節點 204之間的通信。在此項技術中pSMp訊框僅用於存取點與 151920.doc •14- 201141291 使用者站台之間的通信。 同級間異動之排程 圖4說明根據本發明之特定態樣的PSMP訊框内之實例資 訊欄位400。PSMP訊框可定址至群組位址，且可載運若干 站台資訊（STA-info)欄位，可能正傳輸及/或接收資料之每 一使用者站台（STA)有一個站台資訊（STA-info)欄位。 STA-info欄位400之不同攔位可具有不同功能。站台識 別（STA-ID)欄位408可識別與STA-info欄位400相關聯之 STA。PSMP下行鏈路傳輸時間（DTT)開始偏移欄位404可 識別在STA處接收之開始時間’且PSMP-DTT持續時間欄 位406可識別在STA處接收之持續時間。另一方面’ PSMP 上行鏈路傳輸時間（UTT)開始偏移攔位410可識別自STA傳 輸之時間，且PSMP-UTT持續時間欄位412可識別允許自 STA傳輸之持續時間。 每一 STA可能需要確切地知道何時傳輸及接收，以及知 道同級節點之識別碼。在本發明中，提議擴展PSMP訊息 之能力以適應同級間傳輸。在本發明之一態樣中’可將 STA-info類型欄位402之值設定為一已界定之值（例如，為3 之值），該已界定之值指示STA-info欄位400專用於基於直 接鏈路設定（DLS)連接之STA至STA傳輸。可利用保留位元 414來界定用於8丁八至8丁八01^傳輸之頻道。可藉由改變保 留位元414之值來切換傳輸頻道。 當STA自AP接收PSMP訊息時，該STA可掃描該訊息以便 找到用於其本身之STA-info欄位。自STA-info類型欄位， 151920.doc -15- 201141291 STA可識別分配之類型（亦即，AP-STA通信或DLS通信）。 若與STA(例如，STA1)相關聯之STA-info欄位被識別為用 於DLS通信，則STA1可搜尋該PSMP訊息以獲取此DLS通 信之一或多個潛在目的地。 一旦已識別潛在目的地（例如，STA2及STA3)，STA1就 可判定是否有STA2及/或STA3之STA-info欄位之PSMP-DTT開始偏移及PSMP-DTT持續時間匹配STA1之PSMP-UTT開始偏移及PSMP-UTT持續時間。若STA1找到與（例 如）STA2相關聯之匹配STA-info欄位，則STA1可開始在所 分配之偏移處且在所分配之持續時間中將資料傳輸至 STA2。 藉由使用（例如）6位元保留欄位（諸如STA-info欄位400之 保留欄位41 4)之3個位元，PSMP訊框亦可用以指示頻道切 換。舉例而言，若4個鄰近的20 MHz頻道可用於AP，則不 同的3位元型樣可指示一或多個20 MHz頻道之不同組合。 應注意，若頻道切換選項可用，則除偏移欄位及持續時間 欄位之外，STA1亦可需要與一或多個其他同級匹配傳輸 頻道。 應注意，STA可能夠在界定於PSMP訊框中之任何時間週 期期間在睡眠模式中操作。此外，STA可能能夠存取不干 擾由PSMP訊框建立之傳輸的任何傳輸之無線頻道，其中 該無線頻道可能並不指示於PSMP訊框中。舉例而言’ STA 可能在未由PSMP訊息涵蓋之無線頻道中競爭。 圖5說明根據本發明之特定態樣的在AP處所執行的用於 151920.doc • 16- 201141291 排程多個通信之實例柽你<λλ丄 & m ί ^ ^ 、

[Prior Art] In order to transfer data between two user stations (STAs) associated with one access point (AP) (e.g., STA1 and STA2), two methods are generally available. In one method, STA1 can send the data to the AP, and then the AP forwards the data to STA2. In another method, STA1 sets a direct link setup (DLS) connection with STA2. The message for the DLS is forwarded via the AP. Once the DLS connection is set, STA1 can send the data packet directly to STA2. Currently, carrier-based multiple access (CSMA)-based contention protocols must be used to transmit frames that are delivered using DLS. However, in the context of the presence of several DLS connections, significant collisions can occur, which can reduce the throughput of the multiple DLS streams.

The invention and its scope are to be construed as being limited only by the scope of the appended claims. Example Wireless Communication System The techniques described herein are applicable to a variety of broadband wireless communication systems, including communication systems based on orthogonal multiplexing schemes. Examples of such communication systems include orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and the like. The OFDMA system utilizes an Orthogonal Frequency Division Multiplexing (OFDM) 'Orthogonal Frequency Division Multiplexing (OFDM) system to split the entire system bandwidth into a plurality of orthogonal subcarrier modulation techniques. These subcarriers may also be referred to as carrier frequency bins, frequency bins, and the like. In the case of OFDM, each subcarrier can be independently modulated by the data. SC-FDMA systems may utilize interleaved FDMA (IFDMA) for transmission on subcarriers spread over the system bandwidth, local FDMA (LFDMA) for transmission on blocks of adjacent subcarriers, or enhanced FDMA (EFDMA) ) to transmit on multiple blocks of adjacent subcarriers. In general, 151920.doc 201141291, the modulation symbols are transmitted in the frequency domain by OFDM, and the modulation symbols are transmitted in the time domain by SC-FDMA. A specific example of a communication system based on an orthogonal multiplexing scheme is a wiMAX system. WiMAX, which stands for Worldwide Interoperability for Microwave Access, is a standard-based broadband wireless technology that provides high throughput broadband connections over long distances. Today's WiMAX has two main applications: fixed wiMAX and mobile WiMAX. For example, fixed WiMAX applications are point-to-multipoint, allowing broadband access for home and business. Mobile WiMAX provides full mobility for cellular networks at broadband speeds. IEEE 802.1 6x is an emerging standards organization that defines the air intermediaries for fixed broadband wireless access (BWA) systems and mobile broadband wireless access (BWA) systems. IEEE 802.16x approved "IEEE P802.16d/D5-2004" for fixed BWA systems in May 2004, and "IEEE P802.16e/D12 Oct. 2005" for mobile BWA systems was announced in October 2005. . The latest revision of IEEE 802.16, "IEEE P802.16Rev2/D9 March 2009" (Standard Draft), now incorporates material from IEEE 802.1 6e and errata. These standards define four different physical layers (PHYs) and one media access control (MAC) layer. The OFDM and OFDM layer in the four physical layers are the most popular in the fixed BWA area and the mobile BWA area, respectively. The teachings herein may be incorporated into various wired devices or wireless devices (e.g., nodes) (e.g., Implemented in or performed by such devices). In some aspects, a node implemented in accordance with the teachings herein may include an access point or an access terminal. 151920.doc 201141291 Access Point ("AP") may include, be implemented as or referred to as NodeB, Radio Network Controller ("RNC"), eN〇deB, Base Station Controller ("BSC"), base transceiver Station ("BTS"), base station ("BS"), transceiver function w ("TF"), radio router, radio transceiver, base = service set ("BSS"), extended service set ("ESS" ), a radio base station ("RBSj") or some other term. An access terminal ("AT") may include, be implemented or referred to as an access terminal subscriber station, a subscriber unit, a mobile station, a remote station , remote terminal, user terminal, user agent, user device, user device or some other terminology.

For example, an antenna group can include antennas 104 and IG6's another group can include antennas (10) and (4), and - additional groups can include antennas U4. Two antennas are illustrated for each antenna group; more or fewer antennas are available for each-group. Those skilled in the art will appreciate that 'base station 102 can additionally include a transmitter key and a receiver chain, each of which can in turn include a plurality of components associated with signal transmission and reception (eg, a processor, Modulators, multiplexers, demodulators, demultiplexers, antennas, etc.). In addition, the base station 1〇2 can be a base station, a super-micro base station, and/or the like. Base station 102 can communicate with one or more devices, such as device 116; however, it should be understood that base station 102 can communicate with virtually any number of devices similar to device 116. As depicted, device 116 communicates with antennas 〇4 and 〇6, where antennas 〇4 and 〇6 transmit information to device 116 via forward link 118 and from the reverse link 12 116 receives the information. By way of example, in a frequency division duplex (FDD) system, the forward link 丨i 8 can utilize a different frequency band than that used by the reverse link 120. In addition, the forward link U8 and the reverse link ι2〇 can utilize a common frequency band in a time division duplex (TDD) system. In addition, devices 122 and 124 can communicate with one another, such as in a configuration between peers. In addition, device 122 communicates with device 124 using links 126 and 128. In a peer-to-peer special network, devices within range of each other (such as devices 122 and 124) are in a baseless station 1 and/or wired infrastructure. Communicate directly with each other in the case of relaying their communication. In addition, the peer device or node can relay the device in the network between the 151920.doc -10- 201141291 ... mode communication and relay the traffic or communication to the device similar to the base base station until the traffic reaches its final The other channels of the destination, these control components can also transmit the information of the control transmission. _ The network of communication networks used between the nodes of the same level can be used to perform wireless (means or nodes. Any number of devices per node can be used) or multiple other nodes Within the range, and = other throttle lines communicate or, for example, in multiple hops: the node hops to the node until the final destination is reached) via communication: he = communicates. For example, a sender node may wish to communicate with a revenue point. To allow for packet transmission of the transmitter section, one or more intermediate nodes may be utilized. It should be understood that any defect may be a sender node and/or a receiver node, and may be substantially i such as 'can be broadcast or communicated at approximately the same time as receiving information) or perform functions of transmitting and/or receiving information at different times. . The node has been transferred from the 4th phase of the communication period of the network to the node directly connected to the 4th connection. The node can be exchanged natively: the package without any encapsulation. According to some aspects, the “no home” node switches to the wireless network without losing its ongoing session. "native" means that there is no new period of time used to provide assistance to maintain = ongoing session operations, or to forward any new incoming requests to establish a current session to the node's current location. The node of the proxy entity may, depending on the aspect, the node may be mobile (e.g., wireless) 'quiet, (e.g., wired) or a combination thereof (e.g., a node is static and 151920. Doc 201141291 Two nodes are mobile, both nodes are mobile, and so on). Figure 2 illustrates a system 2 that allows two nodes to communicate via a wide area network interface and/or device to device interface in accordance with various aspects. The first node (node 1) 202 and the second node (node 2) 2〇4 are included in the system 2〇〇. Each node 202, 024 includes at least two interfaces. The first interface can be connected to a network 2〇6 that provides an Internet Protocol (IP) address. For example, the network can be a wide area network (WAN), a local area network (LAN), a home network, a digital subscriber line (DSL), a cable, a 3Gpp-based technology, a 3Gpp2-based technology, or a network of interest. Any other technology (eg, the Internet) for interoperability and routing. The interfaces of points 202 and 204 can be wired (e.g., device to device), wireless (e.g., WAN), or a combination thereof. For example, the node interface can be wireless and the node 2 interface can be wired, or the node 2 interface can be wireless and the node 1 interface can be wired, both interfaces can be wireless, or both interfaces All can be wired. For purposes of illustration, the first interface of each of the nodes 202, 204 is a WAN interface, 208 and 210. The WAN interfaces 208, 210 provide connections via the network 2-6, as illustrated by links 212 and 214. In addition, each of the nodes 2, 2, 204 includes at least one second interface that is connected to a local area network or a multi-hop mesh network having a directly connected peer. For example, the local area network can be a wireless local area network (WLAN) or another device-to-device (e.g., peer-to-peer) technology. The second interface of each of the nodes 202, 204 is illustrated as a device-to-device (D2D) interface 216, 218 for purposes of illustration. The D2D interface 216, 218 allows the node 2〇2, 151920.doc 12 201141291 204 to perform direct communication 'which is illustrated by the direct link 220. A procedure for starting a session via network 2〇6 and moving to a direct session (e.g., via direct link 220) will now be described. For purposes of example, node 1 202 is assumed to utilize action. Internet Protocol. Node ι 202 performs communication using its mobile IP address as the source address. The home address is a unicast routable address assigned to a node and serves as a permanent address for the node. Node 1 202 transmits and receives packets via respective first interfaces (eg, WAN interfaces 208, 210). Communication with node 2 204 is via network 2〇6 (e.g., WAN). The packet may be encapsulated in a Μιρν6 tunneling to a home agent (which may be included in the network 2〇6 according to various aspects) or directly to the route optimization tunneling of the node 2 204. FIG. 3 illustrates an exemplary first communication device 3A in accordance with an exemplary aspect. The exemplary first communication device 3 is (for example) a diagram! One of the wireless communication devices (102, 116, 122, 124) or one of the wireless communication devices (202, 204) of FIG. The first communication device 300 includes a processor 302 and a memory 304 coupled via a bus bar 3〇9 through which various components (3〇2, 304) can exchange data and information. The communication device 3 further includes an input module 3〇6 and an output module 308 that are not coupled to the processor 302 as illustrated. However, in some aspects, the input module 306 and the output module 308 are located inside the processor 302. The input module 3〇6 can receive an input signal. Input module 306 can (and indeed does, in some aspects) include a wireless receiver and/or a wired or optical input interface for receiving input. The output module 〇8 may include (and indeed include, in some aspects) a wireless transmitter for transmitting output and/or a wired 151920.doc • 13-201141291 or optical output interface. The processor 302 is configured to: receive a first signal from a second communication device, generate a first application alarm when the first signal satisfies an application alarm criterion; and receive a second signal from the -access point, The second signal carries a second communication device based on the previous signal from the second communication device. The access point of the hole can be (and sometimes is) a base station. In some aspects, the second communication device information is location information. In various aspects, as part of the configuration to receive the -th signal, processor 3G2 is configured to receive the first signal via the wireless inter-level interface. In some aspects, as part of the configuration to receive the second signal, processor 302 is configured to receive the second signal via a wireless wide area network interface. The processor 302 is further configured to determine an operation to be taken based on the second communication device information included in the second signal and the information included in the first signal. In an exemplary aspect, the second communication device information included in the second signal is the information about the previous address of the second communication device, and the information included in the first number 5 is the current location information. And the operation is one of a location-based traffic update operation and a location-based advertisement update operation. In some aspects, the processor 〇2 is further configured to respond to the generated first application alert. An information request signal is sent to an access point requesting information corresponding to the second communication device. Certain aspects of the present invention support the use of a power management architecture (e.g., a power save multi-round (PSMP) frame) for Ap-based scheduling of inter-level communication, such as illustrated in Figure 2. Communication between the wireless node 2〇2 and the wireless node 204. In this technology, the pSMp frame is only used for communication between the access point and the 151920.doc •14-201141291 user station. Scheduling between peers Figure 4 illustrates an example information field 400 within a PSMP frame in accordance with certain aspects of the present invention. The PSMP frame can be addressed to the group address and can carry several STA-info fields. Each user station (STA) that is transmitting and/or receiving data has a station information (STA-info). ) field. Different blocks of the STA-info field 400 can have different functions. The Station Identification (STA-ID) field 408 identifies the STA associated with the STA-info field 400. The PSMP Downlink Transmission Time (DTT) Start Offset field 404 can identify the start time 'received at the STA' and the PSMP-DTT Duration field 406 can identify the duration of reception at the STA. On the other hand, the 'PSMP Uplink Transmission Time (UTT) Start Offset Block 410 can identify the time since the STA was transmitted, and the PSMP-UTT Duration field 412 can identify the duration allowed for transmission from the STA. Each STA may need to know exactly when to transmit and receive, and to know the identity of the peer node. In the present invention, the ability to extend PSMP messages is proposed to accommodate inter-segment transmission. In one aspect of the invention, the value of the STA-info type field 402 can be set to a defined value (e.g., a value of 3) indicating that the STA-info field 400 is dedicated to STA-to-STA transmission based on Direct Link Setup (DLS) connections. The reserved bit 414 can be utilized to define a channel for 8-8 to 8 D8. The transmission channel can be switched by changing the value of the reserved bit 414. When the STA receives a PSMP message from the AP, the STA can scan the message to find the STA-info field for itself. From the STA-info type field, 151920.doc -15- 201141291 STA can identify the type of allocation (ie, AP-STA communication or DLS communication). If the STA-info field associated with the STA (e.g., STA1) is identified as being used for DLS communication, STA1 may search for the PSMP message to obtain one or more potential destinations for this DLS communication. Once the potential destinations have been identified (eg, STA2 and STA3), STA1 can determine if there is a PSMP-DTT start offset in the STA-info field of STA2 and/or STA3 and the PSMP-DTT duration matches the PSMP-UTT of STA1. Start offset and PSMP-UTT duration. If STA1 finds a matching STA-info field associated with, for example, STA2, STA1 may begin transmitting data to STA2 at the assigned offset and for the assigned duration. The PSMP frame can also be used to indicate channel switching by using, for example, 3 bits of a 6-bit reserved field (such as the reserved field 41 4 of the STA-info field 400). For example, if four adjacent 20 MHz channels are available for the AP, the different 3-bit patterns may indicate different combinations of one or more 20 MHz channels. It should be noted that if the channel switching option is available, in addition to the offset field and the duration field, STA1 may also need to match the transmission channel with one or more other peers. It should be noted that the STA may be able to operate in sleep mode during any time period defined in the PSMP frame. In addition, the STA may be able to access any transmitted wireless channel that does not interfere with the transmission established by the PSMP frame, where the wireless channel may not be indicated in the PSMP frame. For example, the STA may compete in a wireless channel that is not covered by the PSMP message. Figure 5 illustrates an example of a plurality of communications performed at the AP for 151920.doc • 16-201141291 scheduled in accordance with a particular aspect of the present invention, <λλ丄 & m ί ^ ^ , . At 502, ap can determine a plurality of routings between the devices, and the 亥°H scheduling is not used by a first device (ie, a similar lang point) for transmitting the time period. And by a second device, another peer node is used to perform the same time period of receiving. At 504, the AP can transmit the schedule to the first device and the second device. The plurality of communications may include a plurality of DLS communications established between pairs of devices (i.e., between peer nodes). Figure 6 illustrates the use of the first device at the first device in accordance with the features of the present invention. In an example operation 60 of establishing communication with a second device, at 602, the first device can receive a control message indicating that the control message indicates a time period for communication. At 6:4, it can be performed along the 丨g 士Λ A second device is identified that has the same time period assigned for communication, such as H^: each device is at 6〇6, and the first device can communicate with the second device during the time period. Change between the same level of the starting AP schedule ☆ In order to make the - access point schedule one or more different levels The access point may need to know the accumulated inter-level traffic at the STA (baeklQged(4)). In the present invention, several methods are proposed for providing accumulated information to Ap. In the sample, the AP can listen to the DLS data service to determine the accumulated information, wherein the accumulated information can be used to schedule future data transmission. In another aspect, Ap can use a deterministic backoff procedure. Scheduling the transmission time of the request for DLS transmission. Ap may issue a message with a backoff count for a subset of STAs with DLS capability' and then the AP may wait for a response related to the inter-level buffer level. 151920.doc -17 - 201141291 In another aspect, the AP may utilize the Traffic Conditioning Specification (TSPEC) information of the DLS stream to determine how often a particular DLS stream needs to be scheduled. The various operations of the methods described above may be performed by any of the functions capable of performing the corresponding functions. The components may be implemented as a suitable component. The components may include various hardware and/or software components and/or modules including, but not limited to, circuitry, special application integrated circuits (ASICs), or processors. In general, in the presence of the operations illustrated in the figures, '5Hai et al. may have correspondingly numbered corresponding component plus functional components.
